The elbow is considered a third class lever because the effort is applied closer to the fulcrum than the load.

Explanation:

On a third class lever the power exercised is between the point of support and the resistance.

The elbow is the joint between the arm and forearm, similar to a clamp, performing predominantly flexion and extension movements.

The elbow joint is considered a lever of this type as:

In this case, the elbow is characterized because the effort is closer to the fulcrum - the elbow or point of support - than to the load.

- The effort is applied further from the fulcrum than the load and the fulcrum is in the center of the lever correspond to other types of leverage.

- The elbow is used to lift objects, is a general function of the upper limb.

the plates spread at mid-ocean ridges (they are divergent plate boundaries) which allows magma to rise through the weakness between the plates. the magma then emerges as lava from the boundary and cools, creating a new crust.
